Abstract

L'invention concerne un agencement de réflecteur (2) réglable d'un dispositif d'éclairage de véhicule à moteur comportant un réflecteur (4) disposé sur un support (12) et destiné à la réflexion de la lumière. Une section d'articulation (10) fixe le réflecteur (4) au support (12) de telle sorte que le réflecteur (4) peut tourner autour d'un centre de rotation (14) fictif. Le réflecteur (10) s'appuie sur le support (12) de manière à empêcher toute rotation du réflecteur (4) autour d'un premier axe (x) fictif. Un premier moyen de réglage (20), déplaçable par rapport au support (12), vient en prise avec une première partie de butée (24) du réflecteur (4) de telle sorte qu'il permet une rotation du réflecteur (4) autour d'un deuxième axe (y) fictif. Un deuxième moyen de réglage (30), déplaçable par rapport au support (12), vient en prise avec une deuxième section de butée (34) du réflecteur (4) de telle sorte qu'il permet une rotation du réflecteur (4) autour d'un troisième axe (z) fictif.
